Findings from a new Associated Press-GfK poll conducted Jan. 17-21:

Of those who’ve tried to sign up, or who live with someone who has, 71 percent have encountered problems. But the share reporting success jumped to 40 percent from a meager 24 percent in December. …

Only 4 percent said things were going extremely or very well, while another 17 percent said things were going somewhat well.

Compare that to 38 percent who said the rollout had gone not at all well. Another 28 percent said things were not going too well. Add those together and it makes up two-thirds of the public.
